oItcUIT-conrnomms SWITCH Specification of Letters Patent.

Application filed July 16, 1918. Serial N o. 245,163.

which the following is a full, clear, concise,

and exact description. v

This invention relates to a circuit eontrolling switch, and iits object4 is to provide a simple,.compact, inexpensive .and elieient device which will be adapted to control a large number of independentu electrical circuits.

The device, which is termed an interrup ter, consists of a rotatable spindle to which a cam and a gear are rigidly secured, a motor mechanism for operating the rotary elements, a movable bar arranged to be operated by the rotation of the cam, and a. series ofmovable switch-members arranged to be operated by the movement of the bar. The movable switch-members` to`be operated are contact springs mounted upon, but insulated from. the supporting frame/in.which the spindle is mounted.

The motor mechanism for operating the movable. elements of the interrupter preferably consists of a continuously rotating power shaft connnon to a plurality of interrupters and a pinion carried by the pow-er shaft arranged to mesh with the gear on the spindle. W'ith thisv arrangement it will be observed that each interruptor is a unit and can be driven at any desired speed independent of the other interrupters driven from the same driving shaft, simply by changing the ratio of the pinion and driven gear.

The bar which operates the contact springs is supported by two flat springs, which render the use of pivots unnecessary and in engagement with the cam at all times. i

Referring to the drawing, Figure 1 is a top view of an interrupter constructed in accordance with thisl invention, and Fig. 2 is a front view of said interrupter.

he supporting frame 1 of the interrupter is provided with three flanges 2, 3 and 4 by tached to the frame l and The b i means of which the frame 1 may be fastened to a lat surface by the screws 5,6 and 7 respectively. One end of the frame `l has a forwardly projecting yoke. A vspindle 8 is rotatably mounted in bearings 9 and 10 in the arms 11 and l2 respectively of the yoke. Between the arms 11 and 12 a collar 14 is fastened to the spindle 8 by a set screw 29.

A gear 13 is rigidly secured to the collar 14 in any vwell known manner., The gear 13 meshes with alpinion 17 which is securedto a constantly rotating shaft 1S. A cam 15 to the collar 14 and the is rigidly secured gear 13 by screws 16 which extend through the cam and collar.

' The spindle 8, cam 15,

collar 14 and gear 8 rotate as a complete unit. To assemble Patented Feb. 25, 1919.

this unit, the cam 15 is First fastened to the collar 14 and the gear 13.v bled portion of the unit is placed between the arms 11 and 12 of the yoke. The spindle is next inserted and then the collar is fastened thereto by the set screw 29. The width of the collar together with the Width of the cam and the gear is the san'le'as the distance between adjacent faces of the arms 1l and 12.

is completely assembled no axial movement of the spindle can take place.

A bar 20 carrying a roller 21 at one end thereof, is supported by two Hat springs 22 and 23, one end of each' spring being atthe other end of each spring being attached to the bar 20. The har 20 is arranged so that these springs 22 and 23 keep the roller 21 ofthe bar in engagen'ient with the surface of t-he cam 15. ar 20 is provided with tWo rows of pins 24 ofinsulating material, one row extending longitudinally along the'top of the bar 20 and the'other row extending longitudinally along the bottom ofthe bar 20.

A plurality of sets of contact springs 19 are arranged in a row along the top of the frame 1 and are secured thereto inA any Wellknown manner. A siinilarrow is secured to the bottom side of the framel.

on the top side Then this assem.

with a different set of contact springs of the l frame fipa.

row attached to the bottom side of the This arragement is such that as the cam l5 is rotate-l` the -bar 2() i5 longitudinally moved back and forth. This movementy of the bar 2O iS sufficient to canne the pins 2l to open and close the Contact springs 1). lt will therefore be obvious that it' the shaft, 17 rotates at a'tonstant speed the Circuitsl through the Contact springs 24 will all be interrupted at a constant rate. Also it will be obvious that this rate may be readily changed by merely changing the ratio between the pinion 17 and the gear 13.

What is claimed is:

l. ln combination, a trame, a Yrotatable @am mounted therein, a ba arranged to be moved longitudinally by ther rotation otl sai'd oem, a row of pins on said bar, and a row ot sets o' Contact. springa mounted on said ra1iie,'eaoh pin on said oar being in operative relation with a particular not ot' Contact Springs.

3. ln combination, a traine, a rotatable ram mounted therein, a row ot' notl ot' contact springs, a longitudinall)- movable bar having a pin in operative relation with eaeh individual Het oi Contact springs. and a plu rality ot' ttat texible springs rigi ll \v attaehed to Said frame and bar tor supporting said bar and t'or maintaining it in engagement with the surface, ot' said cam. l
